Add zrl opcode. Keep track of local sizes as well as offsets.

Refactor mcg.h as it's getting a bit big; keep track of register variables.

More rigorous dealing of IR groups; no need for is_generated and is_root any
...
more (but now passes are required to set IR roots properly when changing
instructions).

Much better handling of fragments (no run-time code needed to distinguish them
...
from registers) and better handling of individual hops within a paragraph ---
no more ghastly hacks to try and distinguish the input from the output.

Revamp the array module not to use nasty macros any more. Slightly more verbose
...
to use, but definitely cleaner.

Some instruction selection is now happening.

Procedure compilation now happens after the entire EM file has been read in (so
...
that we can look inside data blocks which might be defined in the future...
sigh, csa and csb). csa and csb no longer generate invalid IR.

Replaced the block splicer with a trivial block eliminator (which rewrites
...
jumps to blocks which contain only a jump). Don't bother storing the bb graph
in the ir nodes; we can find it on demand by walking the tree instead ---
slower, but much easier to understand and more robust. Added a terrible map
library.

Add a bodged in algorithm for converting basic block communication from stacked
...
variables to SSA. Also add dead block removal and block splicing. IR code is
much better now.

Create hacky fake basic blocks for data fragments, used to track which
...
instruction labels descriptor blocks refer to; this allows csa and csb to know
where they're going.

Treebuilder now gets to the bottom of my test file, merrily generating

(probably horribly broken) IR.

Store the EM code up front and build the basic block graph *before*
...
generating the IR code. Lots more IR code.
